Another American Airlines flight was forced to land at JFK yesterday after a row of seats became loose after takeoff — the second such incident in three days.

It was also revealed that a third American flight — from Vail, Colo., to Dallas — had issues with loose seats on Sept. 26.

Now, the struggling airline — which filed for bankruptcy protection in November — said that as many as eight planes could have seat problems.

The airline brought mechanics from its Tulsa maintenance base to New York to reinspect 757s that might have the same issue.

The Federal Aviation Administration has also launched a probe of the loose seats, which The Post revealed yesterday.

The latest incident was on a Miami-bound flight that left JFK at 7:11 a.m. yesterday. The plane was forced to return to New York less than an hour later when seats A, B and C in row 14 began moving around.

A similar incident on a Boston-to-Miami flight forced an emergency landing at Kennedy on Saturday.

The seats “became loose much like the flight that happened on Saturday,” confirmed AA spokesman Mary Frances Fagan. “They seem to become loose on the track that holds them to the fuselage.”

The FAA said the two planes “had recently undergone maintenance during which the seats had been removed and reinstalled.”
